China's next-generation carrier rocket Long March-5 will make debut in Hainan province to undergo its first "practical exercise", said Liang Xiaohong, Party chief of the China Academy of Launch Vehicle Technology recently.

One of the key tasks to be completed is cryogenic propellant test, which is the largest of this kind of test and expected to last more than three months.

The Long March-5 rockets, designed for the final chapter of China's three-step–orbiting, landing and finally returning–lunar program, and for the launches of future space stations, will have a payload capacity of 25 tons to low Earth orbits, or 14 tons to geostationary transfer orbit.
